Nothing about the modern pro game, from the paltry prize funds, and relatively few tournaments to the formats is designed to bring the cream to the top.  I think bowling is a great game, and I have total respect for anyone who is willing to put it all on the line and try to make a career out of the game.  At the same time I am saddened by the fact that so few bowlers with the ability to play at the top levels can find enough incentive to take the risk.
